Landry Fields hopes he eventually runs into LeBron James at Madison Square Garden.

But the first person he encountered Thursday night after being chosen by the New York Knicks with the 39th overall pick of the NBA draft was his 15-year-old sister, Celena.

“I was in my room, sitting there with each pick in the second round, kind of holding my breath,” the former Stanford star said of watching the draft on TV from his family’s home in Long Beach. “Then I ran out of the room and almost head-butted my sister. She was screaming louder than me.

“It was a beautiful moment.”

It was a tougher night for Cal senior point guard Jerome Randle and Saint Mary’s senior center Omar Samhan, both bypassed by NBA clubs. Randle, who led Cal to its first Pac-10 title in 50 years, became the league’s first player of the year to go undrafted.

Fields, who led the Pac-10 in scoring as a senior this past season, is headed to a storied franchise in the midst of trying to rebuild through a deep and talented free-agent pool that includes James, Dwyane Wade, Chris Bosh and Amare Stoudemire.

“The opportunity to play with any of those guys would be amazing,” said Fields, a 6-foot-7 small forward, who said he now will root for the Knicks to win the LeBron sweepstakes. “Definitely. I’m part of an organization now, and you want all the help you can get.”

Fields suggested that it could work for him that he’s a second-round pick and won’t command a huge contract from a team trying to save its money for the marquee names. “I’m just going to go in and work as hard as I can and let everything else take care of itself.”
